I need you to start by checking the exhaust system. Make sure the catalytic converter isn't plugged and causing the noise. Place the vehicle on a flat surface turn the engine off and apply the parking brake and place the transmission in gear so that car won't move. At this point, simply take a rubber mallet and tap on the exhaust system to see where the noise if coming from.

Let me know what you find. If my beliefs are correct, the catalytic converter is loose inside and is causing both the noise and the restriction is causing the diesel sound.
